  Modified files:
    sys/kern             vfs_export.c 
  Log:
  When exiting vfs_export(), delete the "export" option from
  the mount options list with vfs_deleteopt().  At this point, the export
  information is saved in mp->mnt_export, so we can delete
  the "export" mount option from mp->mnt_optnew and mp->mnt_opt.
  
  This fixes read-write/read-only update mounts (mount -u -o rw, mount -u -o ro)
  of NFS exported directories.
  
  For some reason, I could only reproduce the problem with a configuration
  supplied by Andre:
  - "options QUOTA" enabled in kernel config
  - "/ -maproot=root 10.0.1.105" in /etc/exports
